As Nancy Drew would say ... "I'm stuck!" ! I need 2 jesters to activate a puzzle but I only have 1, which I found in the tool bag along with the tweezers. I caught the robot and gave him to the guy, and all of the locations tell me there is nothing more to do there. Where do I find the second jester?

I did give the robot to the uncle and he asked me to bring him his special tools so he could fix it. If the jesters are labelled as puzzle pieces, I only have one, and I'm sure I found that and the tweezers in the toolbox outside because I can't interact with the toolbox anymore. Every time I click on the uncle, he just asks for his special tools.

I'll see if maybe the item I'm looking for is laying around somewhere, but the "Hint" button doesn't point to anything and the Strategy Guide wasn't really much help.

The uncle is holding the robot and all he keeps saying is "please bring me my special instruments so I can repair Jim". I held the thingy that reads minds up to his head and it showed a picture of what looks like goggles. To get the goggles, I need to solve a puzzle and I only have 1 puzzle piece. I also have tweezers and a compass needle in my inventory. The only things I can interact with are the chest puzzle and the uncle.
